Subject: Re: [TN] IAu hardness
Sorry all. I used the IAu subject line for thread following.
To recap: We supposedly have IAu and hard Au on the same board. I was led to believe (by the equipment manufacturer) that nano-identation would be a cost effective way to prove this. It MAY be possible, but not with my sample.
SEM-EDS was part of the project (Phosphorous came in at 7%). The EDS seemed to be working at low levels (it picked up trace Gallium from a FIB cut).
But we didn't find any Cobalt in the contact area, which was unexpected...
It has been quite a learning experience for me. Thanks for the excellent feedback. I believe the moral to the story is: you better trust your offshore fab, because to prove out IPC-4552 and MIL-G-45204 conformance from a completed product is likely cost prohibitive.
